Abstract
A vacuum contact switch controlled by a permanent magnet is a vacuum switch in the switch field of an electric appliance. The vacuum contact switch comprises a casing body (8), a static contact (1), a moving contact (2), a moving contact bracket (7), a moving contact bracket slipper block (6), a slideway (5) of the moving contact bracket slipper block, a vacuum-pumping pipe (9), a sealing cover (10), a magnet (4) at the left side of the moving contact bracket, a magnet (3) on a movable magnet seat on the left side, the movable magnet seat on the left side (11), a magnet (14) at the right side of the moving contact bracket, a magnet (14) on a movable magnet seat on the right side and the movable magnet seat on the right side (12). The vacuum contact switch combines a vacuum body, the movable magnet seats (11)(12) and operating mechanisms of various electric appliance switches to form a high/low voltage AC/DC electric appliance switch and an explosion prevention switch, through magnetic force which enables the moving and the static contact (2) (1) to be absorbed together or separated apart. The invention has the advantages of multiple contacts, low price, flexible and reliable movement, manual or automatic convenience, small volume and other advantages of vacuum switch.
Description
Technical field
The present invention relates to a kind of appliance switch, particularly a kind of vacuum contact switch.
Background technology
Now on the market contact of various appliance switches commonly used all be in airborne, will produce arc light during the contact on-off circuit, easy burn-out contact, the moving contact of existing vacuum contact switch are to utilize flexible gum cover to help moving contact to contact with fixed contact or disconnect, and play the effect of sealing.Flexible gum cover is repeatedly flexible easily to be caused ageing of rubber and breaks and cause switch to scrap, and volume is bigger, generally has only one group of contact in each vacuum body, the cost height.Form by vacuum switch bubble and permanent-magnet operating mechanism in addition, the vacuum switch bubble is fixed on the switch base, moving contact is connected with pedestal by action bars, and the adhesive of permanent magnet and pedestal is controlled with the break-make of separating the electric current by a line bag, finish vacuum switch contact deciliter.Structure is comparatively complicated.
Summary of the invention
Be deficiency and the defective that overcomes prior art, the invention provides the vacuum switch of the permanent magnetism control that a kind of volume is little, cost is low, the life-span is long.The present invention is achieved through the following technical solutions.The vacuum contact switch of permanent magnet control is that the dynamic and static contact of 1-6 groups (2) (1) all is sealed in the vaccum case (8), utilize on moving contact support (7) termination fixing permanent magnet (4) (14) to paste mutually with vaccum case (8) side and corresponding with it removable magnetic receiver (11) (12) between the magnet (3) (13) or same sex magnetic level, produce repulsive force, or opposite pole produces attraction.Thereby moving contact (2) and fixed contact (1) are disconnected or connection.Removable magnetic pole seat (11) (12) is linked to each other with various regular tap operating mechanisms, just constitute various vacuum contact appliance switches.
The vacuum contact switch of permanent magnet control has that volume is little, cost is low, the life-span is long, safe and reliable, how through-current capability big, the arc extinguishing ability is strong, simple in structure, spring is little, deciliter time stable, contact advantage such as, can be widely used in various switches in high pressure, low pressure, interchange, direct current, the explosion-proof field.

Course of action
When making simultaneously one of permanent magnet (3) on can left side moving magnet seat (11) and moving contact support (7) When being like pole between the permanent magnet of upper left side (4), produce repulsive force, the removable magnetic receiver in right side (12) The upper right side magnet (14) of magnet (13) and moving contact support (7) be that opposite pole produces attraction. Two Power makes moving contact support (7) mobile, has so just disconnected quiet, movable contact (1) (2), and circuit disconnects; When Another piece permanent magnet of the removable magnetic receiver in the left and right sides (11) (12) is switched to and moving contact support (7) On the corresponding position of permanent magnet (4) (14) time, the pole of magnet in left side is different in nature between them, Produce attraction, the right side pole of magnet is the generation repulsive force of the same sex. Make moving contact support (7) mobile, make Contact (2) and stationary contact (1) close contact, circuit turn-on. With the removable magnetic receiver in the left and right sides (11) (12) Suitably be connected synchronization action just can consist of the vacuum that various permanent magnets control and open with various switch operating mechanisms Close.
Embodiment
Select suitable engineering plastics shell molds once on mould for use, after will being assembled into one with the moving contact support of engineering plastics moulding and moving contact again, and at the support two ends each is fixed a permanent magnet (opposite pole is relative) and puts in type shell, will be stained with bracket slide with seccotine on the moving contact support groove more afterwards.Groove and shell with the capping of engineering plastics sticks together with seccotine at last.Vacuumize back the connection with vacuum-pumping tube of curing etc. gluing connecing with vacuum pump.Seal close vacuum-pumping tube after reaching vacuum degree.This moment, two groups of again that magnetic pole is opposite each two blocks of permanent magnets respectively were fixed on the removable magnetic receiver in the left and right sides, suitably control the spacing of two blocks of magnet, satisfying the stroke requirement of switch operating mechanism, magnet can select for use magnetic field intensity 3000-6000 Gauss's high strong magnet and suitable configuration with the requirement of satisfying the operating mechanism stroke and the requirement of magnetic pull and repulsive force.
